FAQs
What is Pulverized Rotomoulding Powder?
Pulverized Rotomoulding Powder is Linear Low-Density Polyethylene (LLDPE) powder that has been finely ground through pulverization for use in rotational molding (rotomoulding). This process ensures uniform particle size and enhances flowability, fusion, and surface finish in the final molded product.
What is the difference between Pulverized Rotomoulding Powder and Granules?
Pulverized Powder:
- Fine particle size (200-500 microns).
- Better distribution in the mold.
- Faster melting and fusion.
Granules:
- Larger particle size (1-5 mm).
- Requires additional pulverization before use.
- Slower melting and fusion.
What is the significance of particle size in rotomoulding powder?
Ideal particle size: 200-500 microns.
Smaller particles (≤200 microns) → Improve surface finish but may increase air entrapment.
Larger particles (≥500 microns) → Enhance structural strength but may cause poor fusion.
What is the pulverization process in rotomoulding powder production?
Pulverization is a size reduction process where LLDPE granules are ground into fine powder using:
Cryogenic Pulverization – Uses liquid nitrogen (LN₂) for brittle grinding.
Ambient Pulverization – Uses rotating disc mills for mechanical grinding.
What are the key technical properties of Pulverized Rotomoulding Powder?
| Property | Typical Value | Standard |
| Base Polymer | LLDPE (Linear Low-Density Polyethylene) | – |
| Density | 0.918 – 0.939 g/cm³ | ASTM D792 |
| Melt Flow Index (MFI) | 3-7 g/10 min (190°C, 2.16 kg) | ASTM D1238 |
| Bulk Density | 0.35 – 0.45 g/cm³ | – |
| Particle Size Distribution | 200-500 microns | ASTM D1921 |
| Impact Strength | Good (Varies by formulation) | ASTM D256 |
What is the importance of Melt Flow Index (MFI) in Pulverized Powder?
MFI (Melt Flow Index) measures the flowability of the molten polymer.
Low MFI (3-5 g/10 min) – Higher impact strength, suitable for thick-walled products.
High MFI (6-7 g/10 min) – Better flowability, ideal for thin-walled products.
What are the common applications of Pulverized Rotomoulding Powder?
Industrial Tanks – Chemical storage, water tanks.
Automotive Components – Fuel tanks, dashboards.
Household Items – Dustbins, storage boxes.
Leisure & Playground Equipment – Slides, toys.
How does the bulk density of the powder affect rotomoulding?
Higher bulk density (≥0.45 g/cm³) → Faster settling in the mold, reduces air entrapment.
Lower bulk density (≤0.35 g/cm³) → Ensures better flowability, helps in complex mold designs.
What is the recommended processing temperature for Pulverized Rotomoulding Powder?
180°C – 230°C (Varies based on polymer grade).
Dwell time depends on part thickness.
Cooling rate must be controlled to prevent warping.
Does Pulverized Rotomoulding Powder require additives?
Yes, additives improve performance and durability:
UV Stabilizers (HALS – Hindered Amine Light Stabilizers) → UV protection for outdoor use.
Impact Modifiers → Increase toughness.
Antioxidants (AO – Antioxidant Additives) → Prevents thermal degradation.
Flame Retardants (FR – Flame Retardant Additives) → For fire-resistant applications.
How does cooling rate impact the final product?
Fast cooling → Causes warping and shrinkage.
Controlled cooling → Improves dimensional stability.
Water spray cooling → Helps in uniform solidification.
What are the different grades of Pulverized Rotomoulding Powder?
General Purpose Grade – Standard LLDPE-based powder for common applications.
UV-Stabilized Grade – Contains HALS for outdoor durability.
Flame-Retardant Grade – Includes FR additives for fire resistance.
Antimicrobial Grade – Embedded with biocides to prevent microbial growth.
What factors affect the flowability of the powder?
Particle size distribution – Uniform particles flow better.
Moisture content – High moisture causes clumping.
Bulk density – Higher density improves powder movement.
How does moisture affect Pulverized Rotomoulding Powder?
Absorbed moisture causes clumping and poor flow.
Leads to defects like pinholes and bubbles in the final product.
Proper storage in dry conditions is necessary.
How does particle shape impact performance?
Spherical particles → Flow better, reduce air entrapment.
Irregular particles → May cause uneven melting and defects.
Can Pulverized Rotomoulding Powder be used for multi-layer molding?
Yes! It is suitable for:
Double-layer tanks → Inner layer for food-grade safety, outer layer for UV resistance.
Foamed structures → Lightweight products with high strength.
What are the quality control measures for Pulverized Powder?
Particle Size Analysis – Ensures consistency.
MFI Testing – Confirms flow properties.
UV Stability Tests – Determines outdoor durability.
Impact Resistance Tests – Assesses strength.
How should Pulverized Rotomoulding Powder be stored?
Store in dry, cool conditions to prevent moisture absorption.
Use airtight containers to maintain quality.
Avoid direct sunlight to protect UV-sensitive grades.
What are the challenges in using Pulverized Powder for rotomoulding?
Moisture absorption → Causes molding defects.
Powder segregation → Affects uniformity.
Excessive fine particles → Leads to air entrapment.
